Question
left on the forest floor of the SimBody Farm for an unknown period of
time. Your challenge is to estimate how long they've been dead (the
postmortem age).
You are given the SLOPE and INTERCEPT of the best fit line (under
the graph), so you can use this information in the form of y = mx + b,
where y is concentration of ammonia, x is cadaver age in hours, m is
slope and b is y-intercept. To estimate body ages, substitute ammonia
concentration as the y value and solve for x (age).
For example, the ammonia concentration in the vitreous humor for the
body at the top is 12.8 µg/mL.
